Port to 3.1 - Fix out of range access in GetRecycleMemoryInfo (#27959)
Ports change #26873 to release 3.1 branch.
On OpenVZ virtualized linux, GetCurrentProcessorNumber which uses sched_getcpu()
can return a value greater than the number of processors reported by
sched_getaffinity with CPU_COUNT or sysconf(_SC_NPROCESSORS_ONLN).
For example, taskset -c 2,3 ./MyApp will make CPU_COUNT be 2 but
sched_getcpu() can return 2 or 3, and OpenVZ kernel can make
sysconf(_SC_NPROCESSORS_ONLN) return a limited cpu count but
sched_getcpu() still report the real processor number.
Example of affinity vs current CPU id on OpenVZ:
nproc: 8
nprocOnline: 1
affinity: 1, 0, 0, 0, 0, 0, 0, 0, cpuid: 2
affinity: 1, 0, 0, 0, 0, 0, 0, 0, cpuid: 2
affinity: 1, 0, 0, 0, 0, 0, 0, 0, cpuid: 2
affinity: 1, 0, 0, 0, 0, 0, 0, 0, cpuid: 2
affinity: 1, 0, 0, 0, 0, 0, 0, 0, cpuid: 2
affinity: 1, 0, 0, 0, 0, 0, 0, 0, cpuid: 5
affinity: 1, 0, 0, 0, 0, 0, 0, 0, cpuid: 5
